Abstract

In a water treatment process and assembly, floating solids are removed from the surface water (O) of waste water in a settlement basin (A) or similar installation. The floating residues are directed by a sub-surface helical conveyer in the settlement basin (A) towards an intermediate holding receptacle (2) with an outlet in its base. The collected residues (FG) are pumped out of the intermediate receptacle (2) from time to time as required.
